NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 619,310, dated February14, 1899. Application filed March 14, 1896. Serial No. 583,165. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, JOHN L. JACKSON, a citizen of the United States,residing in Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Non-Refillable Bottles,of which the following is a specification, reference being had to theaccompanying drawings, in which-- Figures 1 and 2 are vertical sectionsillus Fig. 3 is a horizontal section on line 3 3 of Fig. 1. Fig. lis aplan view of one of the valves shown in Fig. 2.

My invention relates to non-refillable bottles, and has for its objectto provide an improved bottle of this class which will be inexpensiveand will effectually resist attempts to refill it.

To this end my invention consists, first, in providing the bottle-neckwith a suitable recess and arranging in such recess an imperforatenon-removable valve adapted to be put into place after the bottle hasbeen filled; second, in providing the bottle-neck with a suitable valveadapted to prevent filling of the bottle and with a protecting deviceadapted to be non-removably placed in the bottleneck after the bottlehas been filled to prevent interference with the valve; third, in acertain new and improved bottle, and, fourth, in certain otherimprovements to be hereinafter pointed out.

That which I claim as new and of my invention will be set forth in theclaims.

In the drawings, 4 indicates the neck of the bottle, which, as shown, isprovided with an This recess is formed, as shown in Fig. 1, by indentingthe neck of the bottle above and below the point at which the recess isto be made, thereby providing internal projections 6 7, respectively,above and below said recess. As shown in Fig. 1, the bottle-neck isindented more deeply below the recess 5 than above it, so that theinternal diameter of the neck opposite the projection 7 is less thanopposite the projections 6. As shown in Fig. 3, instead of a singleprojection above the recess 5 a series of projec tions 6 is formed,leaving channels 8 between said projections 6, the object of which willbe hereinafter stated.

9 indicates a valve. The valve 9 is composed of upper and lower disks 1O11, of inelastic material, and an intermediate disk 12, of elasticmaterial, preferably rubber. As best shown in Fig. 1, the lower disk 11is of greater diameter than the upper disk 10, and the intermediate disk12 is greater in diameter than the disk 11. The arrangement is such thatwhen the elastic disk 12 is doubled back over the disk 10 the valve maybe inserted through the bottle-neck past the projections 6 to its placein the recess 5, but it cannot be forced beyond said recess, owing tothe reduced diameter of that portion of the neck. The valve cannot bewithdrawn from the recess 5 because the rubber disk 12 would then befolded back over the edge of the disk 11, thereby increasing itsdiameter to such an extent as to prevent the passage of the valve pastthe projections 6, the diameter of the disk 11 alone being only slightlyless than that of that portion of the bottle-neck immediately above therecess 5. By this construction a valve is provided which may readily beput in place after the bottle has been filled, but cannot be removedwithout breaking the bottle.

As illustrated in Fig. 1, the edge of the rubber disk 12 when releasedfrom the confinement incident to the insertion of the valve through theneck resumes its normal position and rests upon the projection 7, whichforms a seat for it, thereby closing the neck and preventing theadmission of liquids. The best results are secured by making the edge ofthe disk 12 comparatively thin and flexible, so that it will fit snuglyupon its seat. The result is that when it is attempted to fill thebottle the liquid is retained above the valve 9, which effectivelyprevents its passage. Liquid contained in the bottle may, however, bepoured out, as in the operation of pouring the valve 9 rises from itsseat to the upper portion of the recess 5, permitting the liquid to flowaround the edge of the disk 12 and out through the channels 8, the disk12 being of less diameter than the original internal diameter of thebottle-neck,as shown.

While for most purposes sufficient protection against refilling will beafiorded by using valves having the disks 10 and 11 of metal, to betteravoid refilling of the bottle by inverting it and immersing it in theliquid to be introduced thereinto said disks may be made of buoyantmaterial, such as wood,-

ample protection for general use, as the construction of the valve andits arrangement in the bottle-neck are such that the valve cannotreadily be attacked. In some instances, however, in order to makeassurance doubly sure, two valves are provided, the upper onebeingnon-removable and serving as a protecting device to prevent accessto and interference with the lower valve. In Fig. 1 I have shown suchconstruction, the valve 9 already described being used not only toprevent refilling of the bottle, but also as a protecting device for asimilar valve 13, arranged below it in the neck of the bottle. The valve13 is constructed similarly to the valve 9 and is secured in a recess14: between internal projections 15 16, arranged, respectively, aboveand below such recess. The valve 13 is of less diameter than the valve9, and the internal diameter of the bottle-neck at the recess 14 is lessthan at the recess 5, the arrangement being such that the lower valve 13is inserted in place first and afterward the valve 9. Suitable channels17 are provided immediately above the valve 13 for the outflow of liquidfrom the bottle.

Instead of using a valve having the construction above described for alower valve valves of other forms may be used. For instance, in Fig. 2 Ihave shown a lower valve having in some respects the same constructionas the valves 9 and 13, it being provided I with upper and lowerinelasticdisks 18 and 19, respectively, and an intermediate elastic disk20.

21 indicates a central passage, and

22 indicates a valveeseat therein, in which is seated a ball 23, asshown. vents displacement of the ball.

A spider 24: pre- 5 25 indicates i a cylindrical guide which engagesthebottleneck and prevents tilting of the valve. The valve last describedis non-removably secured in position in the same way as are the valves 913; but it will be obvious that instead of a non-removable lower valvevalves of other descriptions may be used, as the upper valve, which isnon-removable, effectually prevents interference with the lower valve.

When only one valve is used, such valve is non-removably secured inplace and has the construction described for the valves 9 and 13. 1Instead of forming the recess 5 by indentin g the bottle-neck above andbelow the point at which such recess is to be formed, as illustrated'i'nFig. 1, other forms of bottles may be used.

In Fig. 2 a'bottle is shown having its neck 26 provided with recesses 2728, formed in said neck from within, and to permit outflow of liquidchannels 29 30 are provided above such recesses, as shown in Fig. 2. Thearrangement is such that in pouring the liquid from the bottle it willflow around the edges of the valve and pass out through the channels 29.

31 indicates an ordinary stopper or cork which may be used to seal thebottle in the usual manner.

Although I have described in detail the construction herein illustrated,I do not wish to be limited to such specific details of construction, asmany modifications may be made without departing from the spirit of myinvention.

What I claim as my invention, and desire to secure by Letters Patent, isV 1. In a non-refillable bottle, the combination with a bottle-neck,having a suitable recess the lower margin whereof forms a valveseat, ofa valve seated in said recess, having upper and lower inelastic disks,the lower one greater in diameter than the upper one, and anintermediate elastic disk of greater diameter than the lower disk,whereby said valve may be inserted into said recess and be automaticallysecured non-removably therein, and one or more passages for theoutflowof liquid, substantially as described. I

2. In a non-refillable bottle, the combination with a bottle having arecess in its neck, the bottle-neck being narrower at one side of saidrecess than at the other, the narrower margin of said recess forming avalve-seat, of

. a valve seated in said recess having upper and lower inelastic disks,the lower one greater in diameterthan the upper one, an intermediateelastic disk of greater diameter than the lower disk, whereby said valvemay be inserted into said recess and be automaticallysecurednonremovably therein,and one or more passages for the outflow of liquid,substantially as de* scribed.

3'. In a non-refillable bottle, the combination with a bottle having arecess in its neck, the bottle-neck being narrower at one side of saidrecess than at the other, the lower margin of said recess forming avalve-seat, of an imperforate valve seated in said recess having upperand lower inelastic disks, the lower disk of greater diameter than theupper one,

an intermediate elastic disk, whereby said valve may be inserted in saidrecess of the bottle-neck and automatically secured nonremovablytherein, one or more passages for the outflow of liquid, and aprotecting device arranged above said valve, substantially as described.

4:. In a non-refillable bottle, the combina-' tion with abottle having arecess in its neck, and passages 8 at the upper part of said recess forthe outflow of liquid, the bottle-neck being narrower below said recessthan above it, the lower margin of said recess forming a valve-seat, ofa valve consisting of upper and lower disks 10 and 11, the lower diskbeing ICC diameter than the upper one, and an intermediate elastic disk12, whereby said valve may be inserted through the bottle-neck into saidrecess and be automatically secured nonremovably therein, one or morepassages for the outflow of liquid, and a second valve arranged belowsaid first-mentioned valve to permit only the outflow of liquid,substantially as described.
